In recent years, a large number of manufacturers of plastic wood materials for construction have emerged at home and abroad. They have carried out design and construction explorations on wood plastic light steel structure residences. And poor heat insulation, long construction period, poor living experience, plastic houses can easily cause psychological burden, and low market recognition.

Wall is an indispensable and important part of wooden buildings, and it mainly plays the role of load bearing, enclosure or space separation. The wall has a relatively large proportion in wooden buildings, and the area of the wall is usually more than twice the area of the building. The wall is the key to simplifying the design and construction of prefabricated buildings. The walls of prefabricated buildings need to take into account building safety, protection, and comfort. Architectural frame-shear structure is a combination of frame structure and shear wall structure, absorbing their respective advantages, which can not only provide a large space for building layout, but also have good lateral force resistance. The application of frame-shear structures is still in the preliminary research stage in the world. In addition, modern wood structure is an emerging industry in my country, and the construction technology and construction model are basically copied from foreign countries, while the related research on integrated wood structure with plastic-wood composite material as the main material has not been reported at home and abroad.

Wood-plastic composite material is a new type of material composed of wood fiber and polymer plastic as the main raw materials. It mainly includes polyethylene wood-plastic and polyvinyl chloride wood-plastic. It inherits the dual advantages of plastic and wood materials. It has excellent qualities such as high strength, anti-corrosion, waterproof, fire prevention, various structures, easy processing and easy connection, and is an ideal substitute for solid wood. It is widely used in interior decoration or garden landscape products, such as outdoor plastic wood flooring, plastic wood flower stands, plastic wood gazebos, plastic wood railings, etc. With the continuous expansion of WPC production scale and the continuous improvement of WPC product quality, the products continue to be positioned as outdoor engineering materials or small landscape building materials, with limited application value and limited beneficiary groups. How to apply high-quality WPC materials to modern It has become an important issue for the plastic-wood industry to give full play to its excellent performance and better serve the society in wood-structured buildings.

The new heat-insulated plastic-wood wall structure has high shear strength, good heat insulation, sound insulation, and fire prevention effects. It can be produced in modular form and can be prefabricated in the factory, and then transported to the construction site for splicing or connection to build houses. Sound insulation and heat insulation plastic wood integrated frame cut wood wall. Sound insulation and heat insulation plastic-wood integrated frame shearing wood wall, including a glued wood frame connected by glued wood columns and glued wood beams, multiple spaced plastic wood wall studs are fixed in the glued wood frame, and in the glued wood frame The glass fiber cotton glulam frame is filled between the wood-plastic wall studs, and the outside of the wood-plastic wall studs are oriented particle board, breathing paper, and external hanging boards, and the inside of the wood-plastic wall studs are moisture-proof film, gypsum board, inner wall panels. Sound insulation and heat insulation plastic-wood integrated frame shearing wood wall, and sound-absorbing cotton slivers are arranged between the outer side of the glued wood frame and the plastic-wood wall stud column and the oriented strand board. In the sound-insulation and heat-insulation plastic-wood integrated frame shearing wood wall, hanging laths are fixed on the oriented strand board, the hanging laths are located outside the breathing paper, and the external hanging plates are fixed on the hanging laths.

Using wood-plastic wall studs as the main structural material, applied to wood-structured walls, through rational design to take advantage of the material advantages of plastic-wood, the structural advantages of wood structures, and the strength advantages of frame-shear structures, a combination of heat insulation and sound insulation is developed. The wood-plastic integrated frame-shear wood wall with excellent characteristics such as , shear resistance, etc. is of great importance to improve the international market competitiveness of my country’s plastic-wood products, broaden the application fields of plastic-wood products and promote the development of modern prefabricated wood structure buildings. significance.
